People who sell petrol, drugs or alcohol in South Australia's remote Aboriginal communities will face jail terms and large fines under laws to be introduced by the State Government.

The maximum penalty will be 10 years in jail or a fine of up to $50,000.

Aboriginal Affairs Minister Jay Weatherill says the new laws are supported by the Federal Government and the people that run the state's remote Aboriginal communities.

"We still continue to have difficulties with people coming onto the lands and selling alcohol and also supplying petrol," he said.

"When you think about the devastating effect of petrol sniffing on young people then it is important that we make sure that these offences are equally important as some of the offences for heroin and other harder drugs."
